JP2004332701A - High speed rotation control type wind power generation device with windscreen - Google Patents

Abstract

<P>PROBLEM TO BE SOLVED: To make a blade part receiving wind light, thin, long, and large, and to facilitate rotation in a slight wind, and to provide a wind power generation device without damage by a strong wind or centrifugal force, wherein there is no case where installation in a city is not preferable due to trouble of the sound of wind. <P>SOLUTION: A windscreen is attached. Since wind pressure received by the blade is reduced by enlarging the windscreen only when wind is strong, the blade is formed to be light, thin, long and large. <P>COPYRIGHT: (C)2005,JPO&NCIPI

Description

TECHNICAL FIELD OF THE INVENTION
Wind generator
[Prior art]
There are horizontal axis propeller type windmills and Dutch type windmills.
[0003]
[Problems to be solved by the invention]
Do not turn in light winds. In strong winds, the sound of cutting the wind is noisy.
[0004]
[Means for Solving the Problems]
I tried to capture the torque of the wind force rather than the speed. By making the wing part that receives the wind wider, larger, and thinner and lighter, the windmill starts to rotate even in a light wind.
However, if it is thin, light, and wide, it will be broken by wind pressure and centrifugal force when the wind power becomes large.
[0005]
BEST MODE FOR CARRYING OUT THE INVENTION
(1) For the part receiving wind, the vertical wing with the vertical axis as the axis of rotation constantly changes, not always in a fixed direction, or winds that swirl or winds from oblique vertical directions are also effective energy sources. You.
▲ 2 Regarding the part that intercepts the wind, look at the long bolt on the rail, rotate the rail, move the nut on the rail to open and close the windshield, and adjust the wind pressure.
(3) As a driving force for opening and closing the windshield, if the size is small, it transmits the rotation of the rail via the centrifugal clutch to the rotation of the rail, and if it goes down, the rail rotation is returned using the inertia of the spring coil. can do.
▲ 4 ▼ In case of large size, the windshield can be opened and closed by driving the motor.
[0006]
【Example】
Utilize natural energy by installing it on the roof of buildings, roofs of houses, and telephone poles.
[0007]
【The invention's effect】
▲ 1 ▼ Because it is based on weak rotation, it starts generating electricity even in a breeze, so it takes more time to generate electricity, making it more practical.
Although it seems that the amount of power generation is small corresponding to the weak wind, it can be adjusted by the size and the number of installations.
(2) In addition to measures against wind damage to mitigate winds in buildings, it is a method of generating electricity using natural energy, so there is no need to limit the installation location, and there is no area where power is supplied and power is not supplied in urban areas. Power supply, and measures such as measures against global warming, depletion of resources such as petroleum, and measures to reduce dependence on nuclear power, etc., are effective in protecting the global environment and improving the living environment.
[Brief description of the drawings]
[Figure 1] A windshield is attached to the outside of the wing attached to the rotating shaft in the center of the plan view. The wings are made of large, thin and light materials such as carbon fiber sheets and resin films.
Fig. 2 Elevation view (when light wind)
The windshield is closed.
You can receive more wind.
Fig. 3 Elevation view (when strong wind)
With the windshield spread. The area where the wind hits the wings is reduced, and the strong wind and windshield are expanded. Reduces the area where the wind hits the wings, preventing damage to the wings due to strong winds and centrifugal force.
FIG. 4 is an enlarged view of a rail and a guide. As one method for raising and lowering a windshield, a long bolt is used as a rail, and a nut is used as a guide to move on the rail. Rotate to move the windshield up and down.
The rails can be opened and closed both up and down by alternately rotating the adjacent rails in the opposite direction.
[Figure 5] Floor plan of machine room The force applied to the rotating shaft is transmitted to the generator on the left side and used for the energy of power generation.
The right side is equipped with a centrifugal clutch. When the rotation of the main shaft is low, the clutch is disconnected and the rail does not rotate, but when the rotation is fast, the rail is rotated by connecting the clutch. In this case, the force transmitted by the chain passes through the left and right sides of the gear, so that the adjacent rails alternately rotate in reverse.
FIG. 6 is an elevational view in the machine room. A coil spring attached to an inertia shaft constantly transmits the rotational force of the rail, thereby closing the windshield spread by strong wind with the rotational force of the spring trying to return. Return to.

Claims (1)

A wind power generator with a windshield that has a small area to block the wind when the air volume is small and increases the area to block the wind when the air volume is large.
